EZ-KIT Lite Hardware Reference
• The expansion port connectors (
P3
,
P4
, and
P5
) are sites for 50-pin
header connectors. These connectors can be used to access the
ADSP-2189M signals for expansion or test purposes. For more
information, see
“Expansion Port Connectors” on page 3-9 .
• The
P6
connector is a 14-pin header connector connects to an
ADDS-218x EZ-ICE in-circuit emulator. Pin 7 should be removed
for keying purposes. For more information, see
“EZ-ICE Connec-
tor” on page 3-12 .
• The
P7
connector is a jack for a 6.35 mm cylindrical plug. It is used
to supply power to the board. The center pin of the jack is 2.5 mm
diameter and should connect to the positive side of the power
source. The outer sleeve of the mating plug must be ground.
• The
P8
connector is a male 9-pin D-Sub connector. It is used to
communicate with a host computer using RS-232 signal levels and
asynchronous serial protocols.
Expansion Port Connectors
Three expansion port connectors (
P3
,
P4
, and
P5
) provide access to the
ADSP-2189M processor’s interface pins, letting you watch data transmis-
sions. The
P3
,
P4
, and
P5
connectors are sites for 50-pin header
connectors. These connectors can be used to access the ADSP-2189M sig-
nals for expansion or test purposes. In addition, all interrupts, bus signals,
and
PWT_EVENT
signals are available through the expansion port. The pin
numbers on these connectors are arranged as follows.
